摘要: 针对城市主干道网构建虚拟交叉点和虚拟路网,采用虚拟路网OD迭代反推技术,获得各虚拟节点间的现状出行量;利用交通均衡模型对其均衡配流,获得虚拟路网各单元的均衡结构参数。在此基础上,通过分析城市干道网存在的布局结构缺陷,给出系统改扩建优化方案。为城市干道网改扩建布局规划方案的宏观一体化优化和评价提供理论依据和分析方法。

Abstract: Some hypothesized nodes and hypothesized roads network were established, which depended on the land function, traffic blocking area and trunk roads network of the city. Adopting technology of OD iterative procedure, the OD trips of hypothesized network were obtained. Then the equilibrium theory was used to assign the OD trips and to get systemic and structural parameters of this network. Finally, the optimum extending strategy of city trunk roads network was proposed by analyzing those parameters, promoting the integration of the city roads network.

Key words: improving of city trunk roads, hypothesized roads network, reconstruction and extending model of city trunk roads network
